General Considerations for Administration STELARA is intended for use under the guidance and supervision of a healthcare provider . STELARA should only be administered to patients who will be closely monitored and have regular follow-up visits with a healthcare provider. The appropriate dose should be determined by a healthcare provider using the patient's current weight at the time of dosing. In pediatric patients, it is recommended that STELARA be administered by a healthcare provider. If a healthcare provider determines that it is appropriate, a patient may self-inject or a caregiver may inject STELARA after proper training in subcutaneous injection technique. Instruct patients to follow the directions provided in the Instructions for Use . The needle cover on the prefilled syringe contains dry natural rubber (a derivative of latex). The needle cover should not be handled by persons sensitive to latex. It is recommended that each injection be administered at a different anatomic location (such as upper arms, gluteal regions, thighs, or any quadrant of abdomen) than the previous injection, and not into areas where the skin is tender, bruised, erythematous, or indurated. When using the vial, a 1 mL syringe with a 27 gauge, ½ inch needle is recommended. Prior to administration, visually inspect STELARA for particulate matter and discoloration. STELARA is a colorless to light yellow solution and may contain a few small translucent or white particles. Do not use STELARA if it is discolored or cloudy, or if other particulate matter is present. STELARA does not contain preservatives; therefore, discard any unused product remaining in the vial and/or syringe

Preparation and Administration of STELARA 130 mg/26 mL (5 mg/mL) Vial for Intravenous Infusion (Crohn's Disease and Ulcerative Colitis) STELARA solution for intravenous infusion must be diluted, prepared, and infused by a healthcare professional using aseptic technique. Calculate the dose and the number of STELARA vials needed based on patient weight (Table 4). Each 26 mL vial of STELARA contains 130 mg of ustekinumab. Withdraw, and then discard a volume of the 0.9% Sodium Chloride Injection, USP from the 250 mL infusion bag equal to the volume of STELARA to be added (discard 26 mL sodium chloride for each vial of STELARA needed, for 2 vials- discard 52 mL, for 3 vials- discard 78 mL, 4 vials- discard 104 mL). Alternatively, a 250 mL infusion bag containing 0.45% Sodium Chloride Injection, USP may be used. Withdraw 26 mL of STELARA from each vial needed and add it to the 250 mL infusion bag. The final volume in the infusion bag should be 250 mL. Gently mix. Visually inspect the diluted solution before infusion. Do not use if visibly opaque particles, discoloration or foreign particles are observed. Infuse the diluted solution over a period of at least one hour. Once diluted, the infusion should be completely administered within eight hours of the dilution in the infusion bag. Use only an infusion set with an in-line, sterile, non-pyrogenic, low protein-binding filter (pore size 0.2 micrometer). Do not infuse STELARA concomitantly in the same intravenous line with other agents. STELARA does not contain preservatives. Each vial is for a one-time use in only one patient. Discard any remaining solution. Dispose any unused medicinal product in accordance with local requirements. Storage If necessary, the diluted infusion solution may be kept at room temperature up to 25 °C (77 °F) for up to 7 hours. Storage time at room temperature begins once the diluted solution has been prepared. The infusion should be completed within 8 hours after the dilution in the infusion bag (cumulative time after preparation including the storage and the infusion period). Do not freeze. Discard any unused portion of the infusion solution.

Infections : Serious infections have occurred. Avoid starting STELARA during any clinically important active infection. If a serious infection or clinically significant infection develops, discontinue STELARA until the infection resolves. Theoretical Risk for Particular Infections : Serious infections from mycobacteria, salmonella, and Bacillus Calmette-Guerin (BCG) vaccinations have been reported in patients genetically deficient in IL-12/IL-23. Consider diagnostic tests for these infections as dictated by clinical circumstances. Tuberculosis (TB) : Evaluate patients for TB prior to initiating treatment with STELARA. Initiate treatment of latent TB before administering STELARA. Malignancies : STELARA may increase risk of malignancy. The safety of STELARA in patients with a history of or a known malignancy has not been evaluated. Serious Hypersensitivity Reactions : If a severe or other clinically significant hypersensitivity reaction occurs, discontinue STELARA immediately and initiate appropriate medical treatment. Posterior Reversible Encephalopathy Syndrome (PRES) : If PRES is suspected, treat promptly, and discontinue STELARA. Immunizations: Avoid use of live vaccines in patients during treatment with STELARA . Noninfectious Pneumonia : Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of STELARA. If diagnosis is confirmed, discontinue STELARA and institute appropriate treatment. 5.1 Infections STELARA may increase the risk of infections and reactivation of latent infections. Serious bacterial, mycobacterial, fungal, and viral infections were observed in patients receiving STELARA . Serious infections requiring hospitalization, or otherwise clinically significant infections, reported in clinical trials included the following: Plaque Psoriasis : diverticulitis, cellulitis, pneumonia, appendicitis, cholecystitis, sepsis, osteomyelitis, viral infections, gastroenteritis, and urinary tract infections. Psoriatic arthritis : cholecystitis. Crohn's disease : anal abscess, gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeria meningitis. Ulcerative colitis : gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeriosis. Avoid initiating treatment with STELARA in patients with any clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to initiating use of STELARA in patients with a chronic infection or a history of recurrent infection. Instruct patients to seek medical advice if signs or symptoms suggestive of an infection occur while on treatment with STELARA and discontinue STELARA for serious or clinically significant infections until the infection resolves or is adequately treated

Theoretical Risk for Vulnerability to Particular Infections Individuals genetically deficient in IL-12/IL-23 are particularly vulnerable to disseminated infections from mycobacteria (including nontuberculous, environmental mycobacteria), salmonella (including nontyphi strains), and Bacillus Calmette-Guerin (BCG) vaccinations. Serious infections and fatal outcomes have been reported in such patients. It is not known whether patients with pharmacologic blockade of IL-12/IL-23 from treatment with STELARA may be susceptible to these types of infections. Consider appropriate diagnostic testing, (e.g., tissue culture, stool culture, as dictated by clinical circumstances)

Pre-treatment Evaluation for Tuberculosis Evaluate patients for tuberculosis infection prior to initiating treatment with STELARA. Avoid administering STELARA to patients with active tuberculosis infection. Initiate treatment of latent tuberculosis prior to administering STELARA. Consider anti-tuberculosis therapy prior to initiation of STELARA in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed. Closely monitor patients receiving STELARA for signs and symptoms of active tuberculosis during and after treatment

Malignancies STELARA is an immunosuppressant and may increase the risk of malignancy. Malignancies were reported among subjects who received STELARA in clinical trials . In rodent models, inhibition of IL-12/IL-23p40 increased the risk of malignancy . The safety of STELARA has not been evaluated in patients who have a history of malignancy or who have a known malignancy. There have been post-marketing reports of the rapid appearance of multiple cutaneous squamous cell carcinomas in patients receiving STELARA who had pre-existing risk factors for developing non-melanoma skin cancer. Monitor all patients receiving STELARA for the appearance of non-melanoma skin cancer. Closely follow patients greater than 60 years of age, those with a medical history of prolonged immunosuppressant therapy and those with a history of PUVA treatment

Serious Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with STELARA in clinical trials and postmarketing. Some serious hypersensitivity reactions have occurred during the first intravenous dose of STELARA . If a severe or clinically significant hypersensitivity reaction occurs, discontinue STELARA immediately and initiate appropriate medical treatment

Posterior Reversible Encephalopathy Syndrome (PRES) Two cases of posterior reversible encephalopathy syndrome (PRES), also known as Reversible Posterior Leukoencephalopathy Syndrome (RPLS), were reported in clinical trials. Cases have also been reported in postmarketing experience in patients with psoriasis, psoriatic arthritis, and Crohn's disease. Clinical presentation included headaches, seizures, confusion, visual disturbances, and imaging changes consistent with PRES a few days to several months after ustekinumab initiation. A few cases reported latency of a year or longer. Patients recovered with supportive care following withdrawal of ustekinumab. Monitor all patients treated with STELARA for signs and symptoms of PRES. If PRES is suspected, promptly administer appropriate treatment and discontinue STELARA

Immunizations Prior to initiating therapy with STELARA, patients should receive all age-appropriate immunizations as recommended by current immunization guidelines. Patients being treated with STELARA should avoid receiving live vaccines. Avoid administering BCG vaccines during treatment with STELARA or for one year prior to initiating treatment or one year following discontinuation of treatment. Caution is advised when administering live vaccines to household contacts of patients receiving STELARA because of the potential risk for shedding from the household contact and transmission to patient. Non-live vaccinations received during a course of STELARA may not elicit an immune response sufficient to prevent disease

Noninfectious Pneumonia Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of STELARA. Clinical presentations included cough, dyspnea, and interstitial infiltrates following one to three doses. Serious outcomes have included respiratory failure and prolonged hospitalization. Patients improved with discontinuation of therapy and in certain cases administration of corticosteroids. If diagnosis is confirmed, discontinue STELARA and institute appropriate treatment .

7.1 Concomitant Therapies In trials in subjects with plaque psoriasis the safety of STELARA in combination with immunosuppressive agents or phototherapy has not been evaluated . In trials in subjects with psoriatic arthritis, concomitant MTX use did not appear to influence the safety or efficacy of STELARA. In trials in subjects with Crohn's disease (CD-1 and CD-2) and ulcerative colitis (UC-1), immunomodulators (6-MP, AZA, MTX) were used concomitantly in approximately 30% of subjects and corticosteroids were used concomitantly in approximately 40% and 50% of Crohn's disease and ulcerative colitis subjects, respectively. Use of these concomitant therapies did not appear to influence the overall safety or efficacy of STELARA

CYP450 Substrates The formation of CYP450 enzymes can be suppressed by increased levels of certain cytokines (e.g., IL-1, IL-6, TNFα, IFN) during chronic inflammation. Thus, use of STELARA, an antagonist of IL-12 and IL-23, could normalize the formation of CYP450 enzymes. Upon initiation or discontinuation of STELARA in patients who are receiving concomitant CYP450 substrates, particularly those with a narrow therapeutic index, consider monitoring for therapeutic effect or drug concentration and adjust the individual dosage of the CYP substrate as needed. See the prescribing information of specific CYP substrates. A CYP-mediated drug interaction effect was not observed in subjects with Crohn’s disease

Allergen Immunotherapy STELARA has not been evaluated in patients who have undergone allergy immunotherapy. STELARA may decrease the protective effect of allergen immunotherapy (decrease tolerance) which may increase the risk of an allergic reaction to a dose of allergen immunotherapy. Therefore, caution should be exercised in patients receiving or who have received allergen immunotherapy, particularly for anaphylaxis.
